3.3.1
A first order low-pass anti alias filter is provided at the input of the ADC. The ADC is a
sigma-delta modulator of second order using a clock rate of 15.36 MHz. During normal
operation the ADC evaluates the signal at AINx and BINx. The ADC evaluates the signal
at AOUTx and BOUTx while the analog loop-back is activated.
The maximum peak input voltage between AINx and BINx is defined as the minimum
input voltage that results in a continuous series of high or low at the PDMx pin. A larger
input signal will be clipped. An increasing positive voltage at AINx - BINx will result in an
increasing number of high states at the PDMx pin. Hence, the maximum positive voltage
at AINx - BINx results in a series of high whereas the maximum negative voltage results
in a series of low. The average percentage of high states obtained with a given input
voltage is referred to as gain of the ADC. It is expressed in %/Volt. The ADC offset is the
difference in % from the ideal 50 % high states with no input signal, transferred back to
the input voltage using the ADC gain.
